Synopsis
========
A vulnerability in mini_httpd could allow remote attackers to execute
arbitrary code.

Background
==========
mini_httpd is a small webserver with optional SSL and IPv6 support.

Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 www-servers/mini_httpd *<= 1.19 Vulnerable!
-------------------------------------------------------------------
NOTE: Certain packages are still vulnerable. Users should migrate
to another package if one is available or wait for the
existing packages to be marked stable by their
architecture maintainers.

Description
===========
mini_httpd does not properly check for shell escapes when parsing HTTP
requests.

Impact
======
A remote attacker could send specially crafted HTTP requests, possibly
resulting in execution of arbitrary code with the privileges of the
process, or allowing for overwriting of files.

Workaround
==========
There is no known workaround at this time.

Resolution
==========
Gentoo discontinued support for mini_httpd. We recommend that users
unmerge mini_httpd:

# emerge --unmerge "www-servers/mini_httpd"

References
==========
